Descriptive statistics and results of testing differences in personality traits and intelligence between RhD-negative and RhD-positive Toxoplasma-infected and Toxoplasma-free male soldiers.

Tau shows effect size and sign, p shows statistical significance measured with partial Kendall. RhD-negative and RhD-positive subjects are coded with 0 and 1, respectively. Therefore, negative Tau means lower test score in RhD-positive subjects. Formal correction for multiple (51) tests was not performed. Theoretically, 2–3 of 51 tests presented in this table should provide false positive results.
